Abstract
An oleophobic composition contains a carbon-fluorine bond containing additive and a thermoplastic polymer. The additive contains sufficient solubilizing segments to compatibilize the bulk thermoplastic and additive, providing debris-phobic molded articles prepared from the composition.
Claims20
A molded article comprising a thermoplastic polymer and an additive, wherein the additive is a fluorinated polyurethane with a non-fluorine containing solubilizing segment that compatibilizes the thermoplastic polymer and the additive.
A composition comprising a thermoplastic polymer and a copolymer composition, wherein the copolymer composition is the reaction product of
- (a) fluoropolymer having an average molecular weight from about 500 g/mol to about 20,000 g/mol, wherein the fluoropolymer is (alpha, omega)-hydroxyl-terminated or (alpha, omega)-amino-terminated, and wherein the fluoropolymer is present in the triblock structure:
- wherein:
- X and Y are independently —CH2—(O—CH2—CH2)p-T, p is 1 to 50;
- T is a hydroxyl or amino terminal group;
- m is 1 to 100;
- and n is 1 to 100;
- (b) one or more isocyanate species, possessing an isocyanate functionality of 2 or greater;
- and
- (c) one or more polyol or polyamine chain extenders, or a reacted form thereof.
A composition comprising a thermoplastic polymer and a copolymer, wherein the copolymer is the reaction product of:
- (a) a fluoropolymer having an average molecular weight from about 500 g/mol to about 10,000 g/mol, wherein the fluoropolymer is (alpha, omega)-hydroxyl-terminated or (alpha, omega)-amino-terminated, and wherein the fluoropolymer is present in the triblock structure:
- wherein:
- X and Y are independently —CH2—(O—CH2—CH2)p-T, p is 1 to 50;
- T is a hydroxyl or amino terminal group;
- m is 1 to 100;
- and n is 1 to 100;
- (b) a second component selected from polyesters, polyethers, and polybutadienes, wherein the polyesters or polyethers or polybutadienes are (alpha, omega)-hydroxyl-terminated or (alpha, omega)-amino-terminated;
- (c) one or more isocyanate species, or a reacted form thereof, possessing an isocyanate functionality of 2 or greater;
- and
- (d) one or more polyol or polyamine chain extenders, or a reacted form thereof;
- and
- the thermoplastic polymer is selected from polystyrene, polycarbonate, polyacrylonitrile, polyamides, acrylonitrile butadiene styrene (ABS), styrene butadiene styrene (SBS), polyesters, polybutadiene, and thermoplastic olefins (TPO).
